Musculoskeletal system in the old age and the demand for healthy ageing biomarkers

Martin Kussmann, Sofia Moco, Sebastiano Collino

Population ageing has emerged as a major demographic trend worldwide due to improved health and longevity. This global ageing phenomenon will have a major impact on health-care systems worldwide due to increased morbidity and greater needs for hospitalizat ...

The journey of resveratrol from yeast to human

Johan Auwerx

The natural polyphenolic compound resveratrol was first discovered in the 1940s. In the recent years, this compound received renewed interest as several findings implicated resveratrol as a potent SIRT1 activator capable of mimicking the effects of calorie ...

Common Mechanisms for Calorie Restriction and AC5 Knockout Models of Longevity

Johan Auwerx

Adenylyl cyclase type 5 knockout mice (AC5 KO) live longer and are stress resistant, similar to calorie restriction (CR). AC5 KO mice eat more, but actually weigh less and accumulate less fat compared to WT mice. CR applied to AC5 KO result in rapid decrea ...

Understanding, modelling and managing longevity risk: key issues and main challenges

Claudia Ravanelli

This article investigates the latest developments in longevity-risk modelling, and explores the key risk management challenges for both the financial and insurance industries. The article discusses key definitions that are crucial for the enhancement of th ...

Calorie restriction: is AMPK a key sensor and effector?

Johan Auwerx, Carlos Canto Alvarez

Dietary restriction can extend life span in most organisms tested to date, suggesting that mechanisms sensing nutrient and energy availability might regulate longevity. The AMP-activated protein kinase (AMPK) has emerged as a key energy sensor with the abi ...

Interference between PARPs and SIRT1: a novel approach to healthy ageing?

Johan Auwerx, Carlos Canto Alvarez

Poly(ADP-ribosyl) polymerases (PARPs) have traditionally been linked to chromosome maintenance and DNA repair. Recent findings identify PARPs as key modulators of metabolism through their influence on SIRT1 activity, hinting to a possible role of PARPs as ...

Engineered aprotinin for improved stability of fibrin biomaterials

Peter Frey, Stephane Kontos, Jeffrey Alan Hubbell, Kristen Lorentz

Fibrin has been long used clinically for hemostasis and sealing, yet extension of use in other applications has been limited due to its relatively rapid resorption in vivo, even with addition of aprotinin or other protease inhibitors. We report an engineer ...

SRT1720 improves survival and healthspan of obese mice

Johan Auwerx, Carlos Canto Alvarez

Sirt1 is an NAD1-dependent deacetylase that extends lifespan in lower organisms and improves metabolism and delays the onset of age-related diseases in mammals. Here we show that SRT1720, a synthetic compound that was identified for its ability to activate ...

Ppargamma2 is a key driver of longevity in the mouse

Johan Auwerx

Aging involves a progressive physiological remodeling that is controlled by both genetic and environmental factors. Many of these factors impact also on white adipose tissue (WAT), which has been shown to be a determinant of lifespan. Interrogating a trans ...
